When you use the app without an account

We receive no personal data. Your settings, calibration profiles, high scores and imported songs are stored only locally in your browser (localStorage) on your own device.

The microphone signal is processed in real time by your browser (Web Audio API) to recognise the notes you play. The audio is not recorded, not stored and not sent over the internet.
